BOBBIN-HOLDER FOR SPINDLES.

SPECIFICATION forming part of Letters Patent No. 495,818, dated April18, 1893.

Application iiled June 20, 1892. Serial No. 437,318. (No model.)

.To all whom iv' may concern:

Be it known that we, EDWARD MAODUFF and JOHN MACDUFF, citizens of theUnited States, residing at Oohoes, in the county of Albany and State ofNew York, have invented new and useful Improvements in Bobbin- Holdersfor Spindles, of which the following is a specification.

This invention has forits object to provide new and improved bobbinholders for spindles, which are efficient in use and of a simpleconstruction, whereby they can be economically manufactured, while theypossess such characteristics that they hold the bobbin and are driven byfrictional contact with the spindles.

The invention consists in the combination with a tapering spindle, of anelastic rubber bobbin-holding-sleeve fitting the spindle and having alateral collar at its lower end, so that the sleeve constitutes apacking on which the bobbin may be placed and securely held without theuse of extraneous devices for this purpose.

The invention is illustrated by the accompanying drawings, in which-Figure l, is a side elevation of a spindle provided with my improvedbobbin holder, the bobbin being shown in section, and Fig. 2, is adetail longitudinal sectional view of the bobbin-holder.

In the drawings the numeral l indicates a tapering spindle, 2 the whirland 3 the bobbin which must be capable of being removed and replaced sothat when supplied with the required quantity of yarn, it can be removedfrom the spindle and an empty bobbin placed thereupon. To accomplishthis without injury to the bobbin, and to avoid the use of yarn,metallic springs and wedges, as a packing medium for holding the bobbinand causing it to revolve with the spindle, I provide an improved holderwhich is composed of a sleeve 4, made of elastic rubber and adapted toit the tapering spindle and be rotated by frictional contact therewith.The sleeve is formed integral at one end with an annular collar 5 andfrom such collar to the opposite end, the sleeve is of tapering form sothat a bobbin can be forced thereupon and caused to revolve byfrictional contact therewith. The bobbin is formed with a tapering borecorresponding with the tapering external sur` face of the sleeve and theannular collar limits the downward motion of the bobbin when placing thelatter in position on the sleeve. By forming the bobbin-holder as asleeve of elastic rubber, it closely hugs the tapering spindle and ispositively rotated by frictional contact therewith, while the elasticnature of the sleeve renders it possible to rapidly remove and replacethe bobbins without danger of injuring the same since the ends which fitthe sleeves do not meet metallic or hard surfaces Which is liable todamage the ends of the bobbins in frequently removing and replacing thesame.

Having thus described our invention, what We claim is- 1. Thecombination with a tapering spindle, of an elastic rubberbobbin-holding-sleeve litting the spindle and formed integral with alateral collar at one end, so that the sleeve constitutes a packing onwhich the bobbin may be placed and securely held, substantially as andfor the purposes described.

2. Ilhe combination with atapering spindle, of an elastic rubberbobbin-holding-sleeve tapering internally and externally and formedintegral with a lateral collar at its largest end, said sleeve fittingthe spindle and constituting a packing on which a bobbin may be placedand securely held solely by friction, substantially as and for thepurposes described.

In testimony whereof We have hereunto set our hands and affixed ourseals in presence of two subscribing witnesses.
